SPECIFICATION forming part of Letters Patent No. 311,664, dated February3, 1885.

Application'filed March 29, 1884. (No model.)

To all whom it may concern:

Be it known that I, ELI MoALLIsrER, of Albia, in the county of Monroeand State of Iowa, have invented a new and Improved Water-Elevator, ofwhich the following is a full, clear, and exact description.

My invention relates to the class of water elevators in which twobuckets counterbalance each other and are operated alternately by aWindlass; and it consists in the combination, with one or more buckets,of a sprocket-wheel, belt-chain, and bail-chains connected with a widelink in the belt-chain, and with the upper port-ion of the bucket, theextremity of the said belt-chain being connected with the side of thebucket near the bottom, the belt-chain and bail-chains being arrangedrelative to each other, so that when the extremity of the belt-chain isbeing drawn to ward the sprocket-wheel the bail-chains will receive aslower motion by being drawn over the shaft of the sprocket-wheel. Theeffect of this operation is to impart to the bucket a differentialmotion which will raise the bottom thereof faster than the top after ithas passed the trough of the well-curb, so that the water will be pouredfrom the bucket into the trough.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure l is a side sectional elevation of my improved water-elevator,and Fig. 2 is a front elevation.

A frame, A, placed over the well, supports a horizontal shaft, B, uponwhich, in the center of the frame, is secured the sprocket-wheel O. Theend of the shaft outside of the frame A is provided with a crank, D, bywhich it is turned. A belt-chain, E, formed of square 1inks adapted tothe teeth of the sprocketwheel 0, is connected at each end with a bucket, F, near the bottom thereof, and upon the outer side. One of thelinks of the chain E near each end of the chain is provided with eyes a,projecting from opposite sides thereof, and bail-chains b connected withthese eyes are attached to opposite sides of the bucket F, near the top,in a line parallel with the shaft B. Across the top of each bucket issecured a curved guard, c, for preventing one bucket from catching uponthe other or upon parts of the frame or sprocket-wheel.

Across the center of the frame A, directly under the shaft B, andparallel with it, is placed a trough, G, which is connected with thespout H, extending outside of the frame A, in position to discharge thewater elevated by the apparatus into a pail or other receptacle. Byturning the shaft B one of the buckets F is raised, while the other islowered, and after it has passed the trough G the bottom of the bucketis raised at the same rate of speed, while the upper end of the bucketremains nearly stationary, being raised only through the distance due tothe winding of the bailchains b partly around the shaft B. This tips thebucket sutiieiently to allow its contents to discharge into the troughG. By reversing the motion of the shaft B the bucket just raised andtipped is first righted and then lowered, and when the other bucketnears the sprocket wheel the operation just described is repeated. Theseoppositely-arranged buckets balance each other, so that the powerrequired to operate the elevator is simply that required to lift thewater. The caps of the journal-boxes of the shaft B are connected by acurved yoke, d, which serves to strengthen the frame A and to protectthe sprocket-wheel G, and to prevent the buckets from being carriedentirely over the sprocketwh'eel.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the bucket of a water-elevator, of a beltchainattached to the sides thereof near the bottom, and bail-chains connectedto the sides of the bucket and to the belt-chains, substantially asdescribed.

2. The combination, in a water-elevator, of a sprocket-wheel, G, bucketsF, belt-chain E, attached to the sides of the buckets near the bottom,and bail-chains I), attached. to opposite sides of the buckets near thetop, and connected with the eyes a, projecting from the belt-chain, asdescribed.

3. The combination, with two oppositelyarranged buckets, F,.belt-chainE, bail-chains Z), and sprocket-wheel O, for operating the same, of thecentrally-arranged trough G, as described.
